Calibrachoa plant named ‘Sunbelkopaho’

ABSTRACT

A new and distinct cultivar of  Calibrachoa  plant named ‘Sunbelkopaho’, characterized by its compact, upright and mounding plant habit; vigorous growth habit; freely branching and flowering plant habit; long flowering period; large white-colored flowers; and good garden performance.

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘Sunbelkopaho’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofCalibrachoa, botanically known as Calibrachoa sp. and hereinafterreferred to by the name ‘Sunbelkopaho’.

The new Calibrachoa plant is a product of a planned breeding programconducted by the Inventor in Higashiomi, Shiga, Japan. The objective ofthe breeding program is to develop new compact, mounding andfreely-branching Calibrachoa cultivars with attractive and unique flowercoloration.

The new Calibrachoa plant originated from a cross-pollination conductedby the Inventor in Higashiomi, Shiga, Japan in April, 2004 of aproprietary selection of Calibrachoa sp. identified as code number9BS81, not patented, as the female, or seed, parent with a proprietaryselection of Calibrachoa sp. identified as code number 9LB65, notpatented, as the male, or pollen, parent. The new Calibrachoa wasdiscovered and selected by the Inventor as a single flowering plant fromwithin the progeny of the stated cross-pollination in a controlledgreenhouse environment m Higashiomi, Shiga, Japan in September, 2005.

Asexual reproduction of the new Calibrachoa plant by vegetative cuttingsin a controlled greenhouse environment in Higashiomi, Shiga, Japan sinceOctober, 2005, has shown that the unique features of this newCalibrachoa are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

Plants of the new Calibrachoa have not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment and cultural practices such as temperature andlight intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Sunbelkopaho’. These characteristicsin combination distinguish ‘Sunbelkopaho’ as a new and distinct cultivarof Calibrachoa:

-   -   1. Compact, upright and mounding plant habit.    -   2. Vigorous growth habit.    -   3. Freely branching and flowering plant habit.    -   4. Long flowering period.    -   5. Large white-colored flowers.    -   6. Good garden performance.

Plants of the new Calibrachoa can be compared to plants of the femaleparent selection. Plants of the new Calibrachoa differ from plants ofthe female parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa are not as trailing as plants        of the female parent selection.    -   2. Plants of the new Calibrachoa have larger flowers than plants        of the female parent selection.    -   3. Plants of the new Calibrachoa and the female parent selection        differ in flower color as plants of the female parent selection        have pink-colored flowers.

Plants of the new Calibrachoa can be compared to plants of the maleparent selection. Plants of the new Calibrachoa differ from plants ofthe male parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa are not as outwardly spreading        as plants of the male parent selection.    -   2. Plants of the new Calibrachoa have larger flowers than plants        of the male parent selection.    -   3. Plants of the new Calibrachoa and the male parent selection        differ in flower color as plants of the male parent selection        have pink-colored flowers.

Plants of the new Calibrachoa can also be compared to plants of‘Sunbelho’, disclosed in U.S. Plant Pat. No. 15,764. In side-by-sidecomparisons conducted in Higashiomi, Shiga, Japan, plants of theCalibrachoa and ‘Sunbelho’ differed in the following characteristics:

-   -   1. Plants of the new Calibrachoa were more compact than plants        of ‘Sunbelho’.    -   2. Plants of the new Calibrachoa were not as outwardly spreading        as plants of ‘Sunbelho’.    -   3. Plants of the new Calibrachoa were more freely branching than        plants of ‘Sunbelho’.    -   4. Plants of the new Calibrachoa had shorter internodes than        plants of ‘Sunbelho’.    -   5. Plants of the new Calibrachoa were more freely flowering than        plants of ‘Sunbelho’.
